The plasma levels of CXCL-4, CXCL-13, CXCL-16 and CCL-24 chemokines in the peripheral, placental, and cord blood of submicroscopic positive women (Placental malaria negative women with submicroscopic infection in peripheral blood) and healthy controls women (Placental malaria negative-women with submicroscopic uninfected peripheral blood) are also presented on Fig 1. This evidence concerns the gene CXCL13 and infection.
